Dear Support team

Could you provide TPS55340-Q1 sepic simulation model for phase margin?

I'm checking below but it did not work.

    Nagasawa-san,

    The forum post your are referring to is a transient model for the device in a SEPIC configuration. You would need an average model with a SEPIC configuration for this device in order to check the phase margin.

    We do not currently have an average model for the TPS55340 or the Q1 version of the device.

    I believe that the TPS55340EVM-147 documentation shows a bode plot measurement for a SEPIC configuration and the application note for the TPS55340 may give you some additional information:

    I hope this information helps.
